I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. diff --cc arch/arm/mm/fault.c index 3b1ba003c4f9,32034543f49c..000000000000 --- a/arch/arm/mm/fault.c +++ b/arch/arm/mm/fault.c @@@ -163,9 -163,8 +163,11 @@@ __do_user_fault(struct task_struct *tsk { struct siginfo si; =20 + clear_siginfo(&si); +=20 + if (addr > TASK_SIZE) + harden_branch_predictor(); + #ifdef CONFIG_DEBUG_USER if (((user_debug & UDBG_SEGV) && (sig =3D=3D SIGSEGV)) || ((user_debug & UDBG_BUS) && (sig =3D=3D SIGBUS))) { --SqJDPA0lBYgnDFWV Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAlsH4h4ACgkQJNaLcl1U h9AN/Af8DHm8jUlDa1D16t8lQPh7+oWpmZJFoK2133n5iHDnmmrZdQDWmOARZPQn nv3NPGmzySF9ZCw/JGXSDqBGaV1LOPDclQxNKbHtT//2Dxvb6uGV2AlI4pi9mGbm Thoy7PDXSW5q0pUEumcFQBtGfJ4E7sSUfJTb52f3uqlf1TTPwOIo8vCf3IbKjoMu TLQecvhhZJedFJUHRyAXR44ZR76BLSvOFJRgT0mkC1Ww2Tp8DoKi/idZejth3umF PtXY2HhmPDPmrQrcFRm2MytvfE2R4UdYRIHN51z4k42L7V4dTVbZ3F29qzoWBLs2 O9ysrEPXMcA8IQBr6g2Ckjp3muLbsw== =k9nm -----END PGP SIGNATURE----- --SqJDPA0lBYgnDFWV--
